NAME

       tep_print_printk, tep_print_funcs, tep_set_test_filters, tep_plugin_print_options - Print libtraceevent
       internal information.

SYNOPSIS

       #include <event-parse.h>
       #include <trace-seq.h>

       void tep_print_printk(struct tep_handle *tep);
       void tep_print_funcs(struct tep_handle *tep);
       void tep_set_test_filters(struct tep_handle *tep, int test_filters);
       void tep_plugin_print_options(struct trace_seq *s);

DESCRIPTION

       The tep_print_printk() function prints the printk string formats that were stored for this tracing
       session. The tep argument is trace event parser context.

       The tep_print_funcs() function prints the stored function name to address mapping for this tracing
       session. The tep argument is trace event parser context.

       The tep_set_test_filters() function sets a flag to test a filter string. If this flag is set, when
       tep_filter_add_filter_str() API as called, it will print the filter string instead of adding it. The tep
       argument is trace event parser context. The test_filters argument is the test flag that will be set.

       The tep_plugin_print_options() function writes a list of the registered plugin options into s.

EXAMPLE

           #include <event-parse.h>
           #include <trace-seq.h>
           ...
           struct tep_handle *tep = tep_alloc();
           ...
                   tep_print_printk(tep);
           ...
                   tep_print_funcs(tep);
           ...
           struct tep_event_filter *filter = tep_filter_alloc(tep);
                   tep_set_test_filters(tep, 1);
                   tep_filter_add_filter_str(filter, "sched/sched_wakeup:target_cpu==1");
                   tep_set_test_filters(tep, 0);
                   tep_filter_free(filter);
           ...
           struct trace_seq seq;
           trace_seq_init(&seq);

                   tep_plugin_print_options(&s);
           ...
